Research on Real-Time Wellbore Pressure Correction Method Considering Parameter Uncertainty
To improve the accuracy and real-time performance of wellbore pressure prediction,Ensemble Kalman Filtering is introduced into the wellbore pressure prediction model,and a real-time correction method considering parameter uncertainty is designed.This model comprehensively considers the uncertain distribution range of input parameters,based on Ensemble Kalman filtering,and uses measured data for real-time correction,improving the accuracy and real-time performance of wellbore pressure prediction.
